Solvent extraction and spectrophotometric determination of molybdenum in iron

Abstract

Studies on the solvent extraction of molybdenuni(VI) with 4methyl-2- pentanol (methyl isobutyl carbinol) shoiwd that molybdenum(VI) can be quantitatively extracted with 50% 4-methyl-2pentanol in benzene from 1 M hydrochloric acid containing 10 M lithium chloride. The metal ion in the organic phase can be determined spectrophotometrically as the orange-red thiocyaflate complex at 465 nm. Solvent extraction of molybdenum(VI) with methyl isobutyl carbinol eliminates most of the drawbacks with other methods. The method is rapid and extremely simple and the tolerance limit for foreign ions is high. (auth)
